exhaust question

[procircuit406ex]

if you have an exhaust with 3 screws in the end cap can you take another endcap and put it on there?

i.e. like putting a yosh endcap on a procircuit pipe

Most likely not. The yoshi is oval. My HMF is round. Most pipes will have different bolt patterns and different diameters.
